Devices in the MAX3483E family (MAX3483E/MAX3485E/  
MAX3486E/MAX3488E/MAX3490E/MAX3491E) a re  
±15kV ESD-protected, +3.3V, low-power transceivers for  
RS-485 and RS-422 communications. Each device con-  
tains one driver and one receiver. The MAX3483E and  
MAX3488E feature slew-rate-limited drivers that minimize  
EMI and reduce reflections caused by improperly termi-  
nated cables, allowing error-free data transmission at  
data rates up to 250kbps. The partially slew-rate-limited  
MAX3486E transmits up to 2.5Mbps. The MAX3485E,  
MAX3490E, and MAX3491E transmit at up to 12Mbps.  
ESD Protection for RS-485 I/O Pins  
±15kV—Human Body Model  
±8kV—IEC 1000-4-2, Contact Discharge  
±15kV—IEC 1000-4-2, Air-Gap Discharge  
Operate from a Single +3.3V Supply—  
No Charge Pump Required  
Interoperable with +5V Logic  
Guaranteed 12Mbps Data Rate  
(MAX3485E/MAX3490E/MAX3491E)  
All devices feature enhanced electrostatic discharge  
(ESD) protection. All transmitter outputs and receiver  
inputs are protected to ±15kV using IEC 1000-4-2 Air-  
Ga p Dis c ha rg e , ± 8kV us ing IEC 1000-4-2 Conta c t  
Discharge, and ±15kV using the Human Body Model.  
Slew-Rate Limited for Errorless Data Transmission  
(MAX3483E/MAX3488E)  
2nA Low-Current Shutdown Mode  
(MAX3483E/MAX3485E/MAX3486E/MAX3491E)  
Drivers are short-circuit current limited and are protect-  
ed against excessive power dissipation by thermal  
shutdown circuitry that places the driver outputs into a  
high-impedance state. The receiver input has a fail-safe  
fe a ture tha t g ua ra nte e s a log ic -hig h outp ut if b oth  
inputs are open circuit.
